4. Setup and Installation

The Fernco 1056-22 Flexible Pipe Coupling is designed for straightforward installation, providing a secure and watertight connection without the need for adhesives or primers.

Components:

• Flexible rubber coupling body.
• Two 300 series stainless steel clamp bands.

Installation Steps:

1. Prepare Pipes: Ensure the ends of the pipes to be joined are clean, free of debris, and cut squarely. The coupling is designed for 2-inch nominal pipe sizes, meaning the inside diameter of the pipe is approximately 2 inches, resulting in a slightly larger outside diameter.
2. Position Coupling: Slide one end of the flexible coupling over the end of the first pipe. Ensure the pipe extends fully into the coupling, reaching the internal stop or a sufficient depth for a secure seal.
3. Connect Second Pipe: Align the second pipe with the coupling and slide it into the other end of the coupling. Both pipe ends should be fully seated within the coupling.
4. Tighten Clamps: Using a screwdriver, nut driver, or torque wrench, tighten the stainless steel clamp bands securely around each pipe end. Tighten until the rubber coupling is firmly compressed around the pipes, creating a watertight seal. Do not overtighten, but ensure sufficient compression to prevent leaks.
5. Verify Connection: After tightening, visually inspect the connection to ensure the coupling is evenly compressed and the pipes are securely held. The connection should be rigid and stable.

This coupling is highly adaptable and can be used to connect pipes of different materials and even different types, such as corrugated pipe to PVC, provided the nominal 2-inch size is maintained. The robust design ensures a strong and reliable connection.

5. Usage Guidelines

Once installed, the Fernco 1056-22 coupling provides a durable and flexible connection for your plumbing system. It is designed to withstand typical pressures and conditions found in drain, waste, and vent applications.

• Ensure the coupling is not exposed to chemicals or conditions outside its intended use, as specified by plumbing codes.
• Avoid excessive bending or stress on the coupling after installation, although its flexible nature allows for minor pipe misalignment.
• This coupling is suitable for both above-ground and underground installations, adhering to local plumbing codes.

6. Maintenance

The Fernco 1056-22 Flexible Pipe Coupling requires minimal maintenance due to its durable construction and corrosion-resistant components.

• Periodic Inspection: Periodically inspect the coupling for any signs of wear, cracking, or damage, especially in exposed installations.
• Leak Check: After initial installation and during routine checks, observe for any signs of leaks around the connection points.
• Clamp Tightness: If a leak is detected or if the connection feels loose, re-tighten the stainless steel clamps. Do not overtighten.
• Cleaning: Clean the exterior of the coupling as needed with mild soap and water. Avoid harsh chemicals that could degrade the rubber material.

7. Troubleshooting

Most issues with flexible pipe couplings relate to installation or improper sizing.

• Leaks at Connection:
  • Ensure clamps are sufficiently tightened.
  • Verify that both pipe ends are fully inserted into the coupling.
  • Check for any damage to the rubber coupling or the pipe ends that might prevent a seal.
• Coupling Does Not Fit:
  • Confirm that the pipes being connected are indeed 2-inch nominal size. Pipe sizing can sometimes be confusing (e.g., PVC pipe's nominal size refers to its inner diameter, not outer).
  • Ensure you have the correct Fernco coupling model for your specific pipe materials and sizes.
• Connection Feels Loose:
  • Re-tighten clamps.
  • Ensure the pipes are adequately supported to prevent movement that could stress the coupling.
